We investigated the neural mechanism of the selective listening with the coherence function between a sound envelope and MEG signals. The results showed the coherence values of the noticed sound became higher than the unnoticed sound and their distribution was different between both hemispheres of the brain depending on sound lateralization. In addition, the voice sound showed comparatively high conference values in the left hemisphere regardless of the sound source direction. By using this analysis method, we plan to develop a BCI system to support a hearing ability.
